Month: 2025-06 — In the nrfconnect/sdk-nrf repository, delivered two high-impact features that improve reliability, predictability, and performance of power and USB/BLE interactions. Implemented a configurable USB Disconnect Grace Period for Power Management to keep restrictions lifted briefly after USB disconnection, enabling a more predictable restart of advertising and related actions. Aligned this behavior with the nrf_desktop application to ensure consistent user experience across the stack (reference commit: 10cd2b9b6c8d13589e03ba0a7adeb556e79a2823). Introduced a project-wide rule to suspend Bluetooth advertising whenever a USBHS connection is active to improve USBHS report rate, with configuration applied across project files (reference commit: cc61e40059fa23525e3c2668331b6b3b5eacd4be). These changes deliver clearer power management semantics, reduce advertising churn during USB activity, and enhance overall system stability and performance.
